Both will need to have the tcase regularly engaging 4WD to keep the servos working properly.

Valve cover gaskets aren't horribly difficult for either engine, so I would get that fixed or do it yourself soon. Do both at the same time either way. Use OEM Toyota stuff.

I paid $4700 for my 2003 with 280k miles on it and thought I got a great deal. So yeah, you did good no matter what.
